XMM-Newton detection of soft time lags in the TDE candidate AT 2018fyk

Wenda Zhang

In this letter we report a tentative detection of soft time lags (i.e. variability of softer photons lags behind the variability of harder photons) in one observation…

Prospects for differentiating extended coronal geometries in AGNs with the IXPE mission

F. Ursini, G. Matt, S. Bianchi +3

X-ray polarimetry can potentially constrain the unknown geometrical shape of AGN coronae. We present simulations of the X-ray polarization signal expected from AGN coronae, assumin…

The Disk Veiling Effect of the Black Hole Low-Mass X-ray Binary A0620-00

Wan-Min Zheng, Qiaoya Wu, Jianfeng Wu +15

The optical light curves of quiescent black hole low-mass X-ray binaries often exhibit significant non-ellipsoidal variabilities, showing the photospheric radiation of the companio…

Impact of Massive Binary Star and Cosmic Evolution on Gravitational Wave Observations II: Double Compact Object Rates and Properties

Floor S. Broekgaarden, Edo Berger, Simon Stevenson +9

Making the most of the rapidly increasing population of gravitational-wave detections of black hole (BH) and neutron star (NS) mergers requires comparing observations with populati…

Estimating the spin of the black hole candidate MAXI J1659-152 with the X-ray continuum-fitting method

Ye Feng, Xueshan Zhao, Lijun Gou +6

As a transient X-ray binary, MAXI J1659-152 contains a black hole candidate as its compact star. MAXI J1659-152 was discovered on 2010 September 25 during its only known outburst.…

Magnetospheric curvature radiation by bunches as emission mechanism for repeating fast radio bursts

Wei-Yang Wang, Yuan-Pei Yang, Chen-Hui Niu +2

Coherent curvature radiation as the radiation mechanism for fast radio bursts (FRBs) has been discussed since FRBs were discovered. We study the spectral and polarization propertie…
